CINCINNATI — Cincinnati Bengals linebacker Preston Brown isn’t sure what’s going on with his old team after hearing news that Buffalo Bills cornerback Vontae Davis retired at halftime of a loss to the Chargers on Sunday.

Brown is enjoying a 2-0 start with the Bengals, while his former Buffalo teammates suffer through an 0-2 start that included a 49-3 setback in the opener against Baltimore, a team Cincinnati beat Thursday while Brown sat out with an injury for the first time in his career.

Davis, a former Colts defensive back who signed with the Bills a few weeks before Brown left for Cincinnati, reportedly got dressed in street clothes during halftime Sunday, said he was “done” and walked out.

“It’s a weird situation,” Brown said Monday. “It’s something I thought I would never hear about. But I’m glad I’m not on that team. There’s some weird stuff going on up there. I don’t know what his mind is about. I haven’t talked to none of those guys, and I don’t want to know.

“I’ve seen people fake injuries and stuff like that to not go back in, but to just retire, it’s pretty weird. I mean to just put your clothes on and retire, that’s pretty funny. I kind of want to see it.”

When asked what is worse, faking an injury or quitting mid-game, Brown couldn’t decide.

“You’ve kind of got to respect the fact he was like, ‘That’s it for me,’ but, it just sounds so weird,” he said. “He couldn’t give them no more. He got scored on early in the game, and I don’t know what that did to him, and then John (Ross) had him all over the internet a couple weeks ago, so I don’t know what’s going on.”

Ross, the Bengals’ 2017 first-round draft pick, beat Davis and another defender on a move to the end zone after catching a deep pass for a 57-yard touchdown in a preseason game against Buffalo last month.

Brown, a third-round draft pick for Buffalo in 2014, spent Week 2 on the bench for the Bengals, ending his streak of 65 straight regular-season games after injuring his ankle in the opener against Indianapolis.
